Using new Service object instead of deprecated execution_path

In selenium 4.9.1 which this repo is using at the moment, a message pops up about execution_path being deprecated:
DeprecationWarning: executable_path has been deprecated, please pass in a Service object

In newer versions of selenium this code doesn't work at all so it should be changed to using the new syntax
